Photo-thermal integrated control burner

Abstract

The invention provides a photo-thermal integrated control burner. The photo-thermal integrated control burner comprises a fuel supply device, an air supply system, a control device, a light intensityinduction device, a temperature induction device and a combustion system, firstly, a light intensity sensor automatically inducts and adjusts the oil (gas) volume and an air door to reach a maximum light intensity value, secondly, according to a set maximum combustion temperature value of different fuels, a temperature sensor inducts a temperature value, the temperature value is compared with theset temperature value, and the air door is fine-tuned again to approach the set temperature value to achieve the integrated control of the light intensity and temperature. The light intensity sensor feeds back a control signal to the control device, an oil door is opened to the maximum supply amount position, so that the air inlet volume is matched with the oil (gas) volume to achieve the maximumlight intensity value, the temperature sensor inducts and detects the combustion temperature, the air door is fine-tuned automatically, so that the actual combustion temperature reaches the set temperature, and the fuel is burned fully.

Description

technical field [0001] The invention relates to a combustion device for industrial boilers, drying and heating equipment, in particular to a combustion device capable of controlling fuel combustion through light and thermal induction. Background technique [0002] The fuel oil and gas burners currently on the market are all fuel oil (gas) atomized and burned under a certain pressure. By observing the combustion state of the flame, mechanically or manually adjusting the damper, pressure or fuel (gas) ) volume and air volume, adjust the combustion state, and the operator will monitor it at any time. The disadvantage of this kind of burner is that the combustion state cannot be detected in time, the fuel is not fully utilized, and even the insufficiently burned smoke can be seen at the smoke exhaust port, which pollutes the environment. In order to adjust the combustion state in time, the staff cannot stay away from the noise comparison Big equipment, bad working environment. ...

The disadvantage of this kind of burner is that the combustion state cannot be detected in time, the fuel is not fully utilized, and even the insufficiently burned smoke can be seen at the smoke exhaust port, which pollutes the environment. In order to adjust the combustion state in time, the staff cannot stay away from the noise comparison Big equipment, bad working environment

The invention patent of patent No. 2018104148186 is mainly a photoelectric control burner, which controls the combustion state by adjusting the air volume through the intensity of light, but the light intensity value is the largest, which is not the state of full combustion. The sensor senses the feedback signal changes and cannot adjust the air volume in time. The opening of the damper is controlled by the light intensity sensor, which cannot guarantee sufficient combustion. Therefore, a temperature sensor is installed to detect the flame combustion temperature and compare the temperature value set by the system. The servo motor automatically adjusts the size of the damper and the fuel supply to achieve the best combustion state.
